化グラステックス成形品にしばしば生じている。Glass fiber is widely used as a reinforcing material for reinforced plastics, and is often used in the form of rows. A large number of glass monofilaments bundled together is called a glass strand, and roving strands are a bundle of glass strands that are wound in parallel into a bundle without twisting. It is usually served as an autumn roll called cheese. If this is to be cut continuously, the rovings must be fed continuously without interruption, and therefore a large number of rovings must be connected to each other beforehand. For this purpose, it is usually necessary to tie one end of one roving cheese to one end of the next roving cheese. Even if the roving is cut using the usual knotting method, the knot remains as a bundle of many strands, resulting in cracking defects in the strand bundle in the reinforced plastic molded product. As a method of solving this problem to some extent, the knotting method shown in 1% Publication No. 49-41494 is known. This knotting method has a practical bonding strength in terms of the tensile strength of the knotted part before cutting, but
Unravelability after cutting (degree of unraveling into individual strands,
In terms of unbundling properties (hereinafter referred to as unbundling properties), although it is better than the normal tying method, it is not satisfactory, and defects caused by insufficient unbundling of the knots between the rovings are caused by reinforced glasstex molding. This often occurs on products.

である。The inventors of the present invention have conducted intensive studies on tying methods that are less prone to such drawbacks and have excellent unbundling properties after cutting, and as a result, they have discovered an improved roving tying method. In other words, when tying one end of one thread to one end of another thread, one thread is divided into two at its end, one of the two halves is used to make a ring, and this ring is tied together. As a boundary, within the ring, the remaining yarn that has been divided into two and other yarns are interlaced in a cross shape, and furthermore, these two types of yarn have two ends. The gist is how to tie the knots.

It is modeled after 1 ton of glass strand bundles of 2 pieces of glass roving cheese each having a thickness of 463 tex (thickness unit means weight in grams per 1000 m of length) and a knot tied according to the present invention. This is shown in the figure. Figure 2 is a special public official published in 49-4149.

品への悪影響は防止されることが明らかである。Using the tying method of the present invention as shown in FIG. 1, a bundle of glass strands having a thickness of 463° is tied at 50 points at 1-coast intervals. As a result of measuring the number of unbundling failures in the knotted portion at this time, it was found that no unbundling failures occurred. Similarly, by tying as shown in Figure 2, a bundle of glass strands k having a thickness of 463 degrees is tied.
As a result of tying at 50 points using a 1 m interval meter and cutting a length of 25 mmK using a normal cutting machine, it was found that the number of unbundled pieces was 6 or more. It is clear that the threads were sufficiently loosened afterwards, and that the adverse effects on the reinforced plastic molded product due to the looseness defects were prevented.

糸条の結び方。[Claims] In the method of tying one end of one thread with one end of another thread, one thread is divided into two at its end, and one of the nine halves is used to make a monkey. , Within the environment with this environment as a boundary, the remaining threads that have been divided into two and other threads are interlaced in a crosswise manner. Furthermore, the method of tying yarns is characterized in that the ends of these two types of yarns pass through a ring formed by the yarn that is not divided into two.
